CARRYING-FRAM E.

SPECIFICATION forming part of Letters Patent N 0. 605,992, dated J une 21, 1898.

To all whom it mag concern:

Be it known that I, HENRIK EMIL HERBERT BoRG'STRoM, a subject of the Grand Duke of Finland, and a resident of Helsingfors, in the Province of Nyland, Grand Duchy of Finland, Empire of Russia, have invented certain new and useful Improvements in Carrying- Frames, of which the following is a specifica tion, reference being had to the accompanying drawings, forming a part thereof, in which similar numerals of reference indicate corresponding parts.

This invention relates to carrying-frames which are adapted for use as supports for palanquins, litters, stretchers, sedan-chairs, and other and similar articles; and the object thereof is to provide a frame of this class whereby a litter, palanquin, sedan chair, stretcher, 'or similar article will continuously be supported in a horizontal position or adjust itself to such position regardless of the position of the frame by which it is supported, a further object being to provide a carryingframe of the class and for the purpose above specified which is adapted to be carried by two or more persons or carriers.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a side view of one form of my improved carrying-frame; Fig. 2, an end view thereof; Fig. 3, a similar end view of a slightly-modified form of construction; Fig. 4, a view similar to Fig. 1 of a modified form of construction; Fig. 5, a similar view of another modification, and Fig. 6 a section on the line 6 6 of Fig. 5.

In the practice of my invention, reference being made toFig. 1, I provide a single pole S, to which is secured at suitable points two pulleys 9, and I also provide a support'lO, which may consist of a palanquin, litter, stretcher, sedan-chair, or other article, or which may serve simply as a support for such articles, and which is adapted to serve as means for carrying a person or any desired object or article, and a rope, cord, or similar device 11 is passed over said pulleys, and the ends thereof are connected with other ropes, cords, or chains 12, which are connected with the opposite corners of the support, this form of construction being clearly shown in Figs.

Application filed February 12, 1897. Renewed April 26, 1898. Serial No. 678,910. (No model.)

1 and 2, and by means of the rope or cord 11 the support 10 may always be held in a horizontal position regardless of the position of the rod or bar 8.

In Fig. 3 I have shown an end view of a slight modification in Which two of the side bars 8 areemployed, said side bars being connected by cross-rods 13, and the side bars 8 are each provided with pulleys 9, which are arranged on each of said side bars, as shown in Fig. 1, and in this case two of the ropes or cords 11 are also employed, as clearly shown, the ends of said ropes being connected with the ends of the support 10, atthe opposite sides thereof. In Fig. 4 the support 10 is provided centrally at each side with upwardly-curved segmental plates 14, which are provided with segmental slots 15, and the frame, which consists of the side bars 8, is provided centrally on each side with depending bars 16, which are pivotally connected at their lower ends with the support 10, at each side thereof, as shown at 17, and said frame is also provided at each side with braces or stays 18 and 19, the lower ends of the latter being connected with the lower end of the vertical bars 16, and" the lower ends of the former being connected with said bars, at or near the mid dle thereof, and the upper ends of each of the braces or stays being connected with the side bars of the frame, and passing through the segmental slot 15 and through the vertical bars 16 at each side are set-screws 20, and by means of this construction the position of the support 10 may be adjusted so as to always remain in a horizontal position regardless of the position in which the frame is held.

In Figs. 5 and 6 I have shown another modification, in-which the main frame consists of two side bars 8, each of which is curved downwardly at the center, and with each of which is connected a frame composed of vertical legs or supports 21, which are united by horizontal bars 22 and braced by diagonal bars 23 and 24, and said frame is also provided centrally with a vertical bar 25, which is connected with the main side bar 8 at 26, and the diagonal bars 23 are also connected with the main side bar 8 and the vertical bar 25 at 26. Placed between the separate side frames thus formed is a support 27, which may be of any desired form and which is adapted to serve as a support for a litter, palanquin,

stretcher, or other device, or which may serve as such a device, and the frame 27 is provided with the downwardly-curved segmental plates 1,4, in which are formed the segmental slots 15, and passing through the bottom and central portions of the side frames at each side are the set-screws 20, and the frame 13 is provided at one end with a handle 28, by which the position thereof may be adjusted when the set-screws 20 are loosened, and in this form of construction the operation, as will be understood, will be the same as that hereinbefore described, and in this form of construction the side frames are also braced by diagonal rods 29, as shown in Fig. 6. The construction of these side frames both in Figs. 4 and 5, however, is immaterial, all that is necessary being to provide suitable side frames in which the support 10 is pivoted.

This device is adapted to be of great use in carrying persons especially over rough, uneven, or hilly ground, and it is evident that many changes in and modifications of the con- I struction herein described may be made without departing from the spirit of my invention I orsaorificing its advantages, and I reserve the right to make all such alterations in and modifications of said construction as fairly come within the scope of the invention. It will also be apparent that two or more persons may carry the frame, and said frame may be carried by persons on foot or on horseback.

Having fully described my invention, I claim as new and desire to secure by Letters Patenti 1. The combination with a suitable bar or frame, of a support for carrying persons, ob-

jects or things, which is connected therewith,

3. The combination with a suitable carrying-frame, of a support pivotally connected therewith,and suspended therefrom said support being also provided with devices whereby it may be held in'a horizontal position, at

all times, regardless of the position of the frame, substantially as shown and described.

4. A carrying-frame, consisting of two separate side frames, between which is mounted a suitable support for a person or object to be carried, said support being provided with a curved or segmental plate adjacent to the frame in which is formed a curved or segmental slot, and a set-screw which passes through said frame, and said slot, whereby the support may be adjusted to, and held in a horizontal position, regardless of the position of the frame, substantially as shown and described.

In testimony that I claim the foregoing as my invention 1 have signed my name, in presence of the subscribing witnesses, th1s 21st day of January, 1897.
